VENTILATING PASSENGER-CARS.
SPECIFICATION forming part of Letters Patent No. 240,658, dated April 26, 1881.
Application tiled February 12, 1881. (Model.)
`To all whom it may concern ger-Gars, of which the following is a specifica-y tion.
The present invention has for its object to supply a passenger-car with pure, cool air free from dust and smoke, and at the same time dispose of the vitiated air in such a perfect manner that it is utterly impossible for the passengers to inhale and reinhale the same air over and over again from each others lungs.
The invention consists in an apparatus for carrying out my method of car-ventilation, which comprises a chamber serving as a'receptacle for Water and ice, a vertical trunk or flue communicating with the external atmosphere for conducting airinto the purifying and cooling chamber, and a vertical tube or lue which serves to conduct theA air from said chamber into a register or distributing-box located near the ceiling of the car. Air-pipes or draft-filles located on the top of the car and opened at each end inclose or contain smaller pipes, which are made with elbows, which may be turned at will, or even by the draft, so that their open ends shall be in the' direction of the draft, or toward the rear end of the car. These smaller pipes serve to deliver the foul air from the interior of the car into the draft-fines on the roof thereof.
In the drawings, Figure l is a longitudinal sectional view of portion of a passenger-car, showing my invention applied thereto. Fig. 2 is a vertical cross-section, and Fig. 3 is aV longitudinal transverse sectional view.
The letter A designates an air purifying and condensing chamber or box, which is preferably located in a corner of a passenger-car, and may be used as a seat. A vertical" tube or flue, B,rising from said chamber A, extends through the roof of the car and carries a suitable airfunnel, a, through which the external air enters, whether the car be in motion or standing l still. The dust7 smoke, and other impurities entering with the air are absorbed or eliminated therefrom by its passage through water contained in the bottom of the chamber. The
purified air, after its passage through the water, ascends through a compartment, C, of the chamber A, which contains ice or some other refrigerating' material. A vertical tube or flue, D, communicating with said ice-chamber, serves to convey the cool or rarefied air into a register-box, E,from whence it is forced out into the car for respiration.
Suitable means or any preferred form of register may be employed for delivering the airl into the car.
It will be apparent that all the airI which euters through the tube B is caused to pass through the Water for thoroughly washing it, and its subsequent passage through the ice or refrigerating medium will tend to purify and condense the same. It follows that when the air is delivered into the car near the ceiling thereof, it will tend to fall toward the seated passengers, because of its increased gravity, due to its purity and temperature, as compared with the heated and respired air, which is ever seeking a higher eleva-tion, due to its increased temperature and vapor.
In order to remove the vitiated or impure air from the interior of the car, I provide the 1ongitudiual conduits or draft-fines F, which are placed on either side of the monitor-top and are made open at both ends. In these draftlines are arranged movable pipes G, which are made with elbows, and are, by suitable devices, capable of being controlled from the interior of the car or even by the draft, so that their open ends shall be in the direction of the draft or toward the rear end of the car. The external air, with its dust and smoke, is caused to course through the draft-flues with the same velocity that the car is passing through the air, and thus it necessarily follows that the foul or vitiated air is dragged out of the car as by a suction-pump by the powerful draft existing in the draft-dues.
The eduction-pipes G, insteadof bein g movable, may be fitted in the draft-fines in a stationarymannerandhavetheir open endsturned in opposite directions. When this is the case the draft-fines or longitudinal exhaust-conduits on the top of the car are provided with selfacting valves, so that the air cannot course through but one-side at a time, according to the direction in which the car is moving.
ICO
In order to remove the cinders and dirty water from the purifying and condensing charnber as often as necessary, l provide the same with a bottom outlet or tube, L, which is pro- -vided with a suitable closing device.
My system of ventilation does not necessitate making any change in existing cars which are heated by steam-pipes or other heating devices; and it will be obvious that during the prevalence of snow and rain the dust and cinders in the air will be intercepted thereby, and not pa-ss into the condensing-chamber. The ice in said chamber is in winter used as a me dium for completely drying and purifying the air before its admission into the car.
The present invention involves a system of ventilation in which the circulation of air is much the same as occurs in the open air under the natural laws governing atmospheric circulation and temperature.
Although I have described my invention in connection with railway passen ger-cars, it will be evident that my system is applicable to other traveling vehicles-such, for example, as the cabins of Steamers.
What I claim is- 1. In an apparatus for Ventilating passengercars and other vehicles, the combination of au air washing and condensing chamber containing water and ice, a vertical iiue communicating therewith and with the external atmosphere, a vertical flue leading into an air-distributing chamber near the top ofthe ear, and discharge-dues communicating with the interior of the car, all substantially as and for the purposes herein described.
2. In an apparatus for Ventilating cars and other vehicles, the combination of a washing and eondensin g chamber containing water and ice, a vertical flue communicating therewith and with the external atmosphere, a vertical flue leading into a distributing or register box near the top of the car, and longitudinal openended draft-dues on the car-roof inclosin g eduction-tubes communicating with the interior ofA 45 the car, as and. for the purpose set forth.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
